PURPOSE:To make radio waves to be received by a radiation conductor element satisfactorily, by arranging a plurality of antenna elements provided with a ground conductor on one side thereof and with the radiation conductor element on the other side and two reflectors corresponding thereto and rotatably. CONSTITUTION:Antenna elements 14, more than one to be set, are provided with a ground conductor 18 on one side of a dielectric plate 16 arranged verti cally and with at one radiation conductor element (microstrip line) 20 on the other side almost horizontally and vertically. At least two reflectors 26 are provided rotatably at the front of the antenna elements 14 corresponding thereto. According to this means, radio waves from a broadcasting satellite is reflected on the reflectors 26 and reaches the radiation conductor elements 20. At this point, as the reflectors 26 are rotatable freely, the angle of the reflectors can be adjusted as desired. Thus, the angle of the reflectors 26 can be adjusted to either or both of the elevation angle and the azimuth according to the recep tion point thereby enabling the reception of radio waves satisfactorily.
